DRS ban for Eau Rouge?

The FIA is investigating whether the Drag Reduction System is suitable to be used at the Eau Rouge corner in Spa-Francorchamps.

DRS was banned earlier this year in the tunnel in Monaco, after several drivers noted that some might take unnecessary risks through the right-hand kink.

The same reasoning applies here. Eau Rouge is a famous high-incline corner, which is taken flat out in the dry conditions, like the Monaco tunnel. However, the risk of a crash here is also high, according to Rubens Barrichello:

"We’re going to see crashes going on, and that’s not the purpose.
"You’re going to gamble. I mean, last year we had to raise the knee to make it
work [referring to F-duct system], and I went through Eau Rouge with one leg, and
that’s not the purpose."

According to Mercedes, the DRS system may be used for up to 63% of the Spa circuit, second only to Monza.
